Willingness-to-Pay and Design of Water Supply and Sanitation Projects: A Case Study

Publication | December 2006

Using a case study, this paper demonstrates the usefulness of willingness-to-pay studies in designing water supply and sanitation projects.

This paper demonstrates the use of contingent valuation survey findings to make informed decisions on design of water supply and sanitation projects, and estimate benefits for project economic analysis. It demonstrates how to

  • conduct validity tests for willingness-to-pay (WTP) estimates;
  • segregate WTP for poor and nonpoor groups;
  • conduct affordability analysis and target poor for special service delivery; and
  • use conjoint analysis to unbundle demand.

The study further shows how the findings are used to assess the overall viability of water supply and sanitation projects.
